CAR-AXLE.

SPECIFICATION forming part of Letters Patent No. 368,547, dated August16, 1887. Application filed April 4, 1887. Serial No. 233,605. (Nomodel.)

To all whom it may concern:

Be it known that I, EDGAR PEOKHAM, of Syracuse, in the county ofOnondaga, in the State of-New York, have invented new and usefulImprovements in Oar-Axles, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of caraxles which are provided withdetachable journal-bearings of the form of sleeves slipped onto the endsof the axles for the purpose of preserving the axle and admitting ofrenewing thejournal-bearings thereof when required.

My present invention consists in an improved construction andcombination of parts which facilitate the removal of the journalbearingsand are also adapted to more securely retain the same on the axle whilein use.

The invention is fully illustrated in the annexed drawings, wherein-Figures 1, 2, and 8 are longitudinal sections of oar-axles embodying myimprovements. Fig. 4 is a detached perspective view of thejournal-bearing. Fig. 5 isa perspective view of the collar by which thesaid journal-bearing is retained on the axle, and Fig. 6 is an end viewof the axle as constructed in the manner shown in Fig. 2 of thedrawings.

Similar letters of reference indicate correspondin g parts.

A represents the car-axle,formed preferably of wroughtiron.

B denotes thejournal-bearing, which consists of a tube mounteddetachably on the end portion of the axle, and is preferably composed ofsteel and case-hardened.

0 represents a collar, which I rigidly secure to the end of the axle,preferably by shrinking it thereon. Said collar abutting against the endof the journal-bearing B serves to securely retain the same on the axle.

To prevent the journal-bearing from turning on the axle, I form theouter end thereof with notches n n or other suitable clutch-face, andform the adjacent face of the collar 0 with lugs or projections lookinginto the notches n n of thejournal-bearing B.

To facilitate the removal of the journalbearing from the axle, I taperthe end portion of the latter from the outer face of the wheel towardthe end of the axle and taper the interior of the tubular journalbearingB correspondingly. By drilling ahole, c, in the axle at the rear end ofthe journal-bearing B, as shown in Fig. 1 of the drawings, and drivinginto said hole a wedge or key, thejournal-bearing B is readily forcedoutward and loosened from its seat on the axle, so as to permit ofreadily removing said journal-bearing.

The retaining-collar C is to be previously removed from the axle byheating said collar, so as to expand it and loosen it on the axlesufficiently to permit of driving the collar off from the axle.

The tapered end portion of the axle I prefer to terminate with acircumferentially-reduced nipple, D, and shrink the collar 0 on saidnipple,thus requiring the collar to be enlarged in thickness andimparting increased strength to the same. The usual shoulder on theinner end of the journal bearing I form of a separate collar, F, which Ialso shrink onto the axle immediately back of the inner end of thejournal-bearing B, as represented in Fig. 3 of the drawings. When theaxle is thus constructed, the car-wheel will either have to be pressedonto the axle before the aforesaid collar is shrunk on the latter or thecar-wheel has to be constructed with a hub which is detachable from thebody of the wheel and divided diametrically and clamped onto the axle.In order to obviate undue enlargement of thejournal-bearings, I form theaxle with circumferentially-rabbeted end portions, A,as shown in Fig. 2of the drawings, and slip the tubular journal-bearings onto the saidrabbeted portions of the axle.

On street-car axles,which require an extra collar on the extremity ofthe axle, I provide the free end of the nipple D with a circumferentialrabbet, a, and shrink on the rabbeted portion a secondary collar, 0,which is sufliciently remote from the collar 0 to form the desiredbearing 72 between them.

If desired to further insure the attachment of the secondary collar 0 tothe nipple D, a washer, d, of sufficient diameter to lap onto theexterior of the said collar,may be secured to the end of the nipple by atap-bolt passing the notches a a, substantially as described and shown.

2. The combination of the axle taperedfrom the outer faces of the wheelstoward the ends of the axle, tubular journal bearings mounted on thetapered end portions of the axle,and collars permanently secured to theends of theaxle and abutting against the tubular journal-bearin gs,substantially as described and shown.

3. The combination of the axle tapered fromthe outer faces of the wheelstoward the ends of the axle and terminating with the nipples D D,thetubular j ournal-bearings B B, mounted on the tapered end portions ofthe axle, and collars permanently secured to the aforesaid nipples,substantially as described and. shown.

4- The combination of the axle tapered from the outer faces of thewheels toward the ends of the axle and terminating with the nipplesDD,the tubular journal-bearings B B,mounted on the tapered end portionsof the axle, and collars permanently secured to the nipples and of agreater diameter than the exterior of the aforesaid journal bearings,substantially as shown and described.

5. The combination of the axle formed with tapered end portionsterminating with nipples D D, tubular journal bearings B B, mounted onsaid tapered end portions and provided with notches n n at their outerends, and collars O O, permanently secured to the nipples and providedwith lugs looking into the aforesaid notches, substantially as shown anddescribed.

' 6. The combination, with an axle, of tubular journal-bearingsdetachably mounted on said axle, and collars shrunk on the axle atopposite ends of each of said j ournal-bearings, substantially asdescribed and shown.

7. The combination of an axle formed with tapering end portions, tubularjournal-bearings formed cylindrical externally and tapered internally tocorrespond to the end portions of-the axle and detachably mounted on thelatter, and collars shrunk on the axle at opposite ends of the saidjournal-bearings, substantially as described and shown.

8. The combination of an axle formed with taperingcircumferentiallyrabbeted end portions, tubular journal-bearings taperedinternally to correspond to the said end portions of the axle andmounted detachably thereon, and collars shrunk on the ends of the axleand abutting against the ends of the aforesaidjournal-bearings,substantially in the manner specified and shown.

9. The combination of an axle formed with taperingcircumferentially-rabbeted end portions terminating withcircumferentially-reduced nipples, tubular journal-bearings taperedinternally to correspond to the aforesaid end portions of the axle andmounted detachably thereon, and collars shrunk on the nipples andabutting against the ends of the said journal-bearings, substantially asdescribed and shown.

10. The combination of an axle formed with circumferentially-redueednipples on its ends, tubular journal-bearings mounted detachably on theaxles back of the nipples, retainingcollars shrunk on the nipples andabutting against the ends of the said journal-bearings,

and secondary collars shrunk on the ends of the nipples remote from theretaining-collars, substantially in the manner set forth and shown. Intestimony whereofI have hereunto signed my name and affixed my seal, inthe presence of two attesting witnesses, at Syracuse, in the county ofOnondaga, in the State of New York. EDGAR PEGKHAM.
